The main object of theinvention is the provision of'meansfor the purpose specified which shall be of simple construction, have the fewest possible parts, be eflicient and practically noiseless in operation, durable and not liable'to become inoperative, and capable of rotating a shaft in the same direction not only when the reciprocatingmeans moves forwardly, but also when the same moves rearwardly.

A'further object is the provision of means for the purpose specified wherein the use of springs is eliminated and which has no dead center or centers. y

A further object is the provision of efficient means of the character mentioned whichshall be adapted to operate a great variety of mechanisms or machines, such as washing machines, wringers, grindstones, pumps, post and pile drivers, invalid chairs, hand cars, etc.,' etc. A specific and very important use for whichthe means is adapted is the automatic regulation of windmills for pumping water, as hereinafter set forth, and other similar purposes wherein automatic control is desired. I

A further object is the provision of means of the character specified which shall be adapted to beoperated by a hand lever, a windmilha steam engine, by ocean waves, and other mechanical powers.

The'invention consists in certain novelties of construction and in the combinations of parts as herein set forth andclaimed.

The accompanying drawings illustrate an example of the embodiment of the'invention, the same being constructed and the parts combined according to the best mode of procedure I have so far devised for the practical application of the principle.

ing the transforming means when operated by a hand lever and when energy is to be transmitted to another machine or device by a sprocket wheel'or a drum.

Figure 2 is a top plan view of Figure 1, the hand lever being in section.

Figure 3 is a side view of the transforming means partly in section, the supporting frame being omitted.

Figure i is a side view in elevation of one of the pawl-supporting means.

Figure 4: is an edge view of Figure 4.

Figure 5 is an end view of the clutch mechanism in Figure 2 for throwing the drum into and out of gear.

Referring to the figures, A A are two parallel members of any suitable material united by base piece B B and bolts 0 constituting a conventional frame for supporting the transforming means, the type of frame being varied as circumstances may warrant. D designates a hand lever mounted upon a fulcrum bolt E supported in the frame. F is a rotary shaft passed through the members A, A and in practice having suitable bearings. On the shaft at one side is a sprocket wheel G secured to the shaft by a cotter pin H passed through the hub and shaft. When the sprocket wheel is not to be used the cotter pin is removed and inserted in the hole I so the shaft will not transmit motion to the wheel.

On the shaft F at the other side is a drum K normally loose on the shaft, which can interlock with a sleeve or member L, fixed on the shaft, through the medium of interlocking teeth or offsets M, as clearly shown by Figure 2. Means for shifting the drum into and out of gear consists of the lever N forked at one end and pivoted by pivot pin 0 outside of and to a U-shaped yoke member P which is held in place by a nut or washer R, which nut or washer also limits the outward movement of the lever.

To the lever N is loosely pivoted by pin S a shifting lug T the end of which is seated within groove U at one end of the drum. On the lug T is a pin carrying a helical spring V which bears against a seat on a lug W carried by the lever arm. The spring normally a V ,wi1-;hom; 5pm
